So I managed to install it and the mpirun problem was indeed a problem on my computer and not on the package per se. I'll give workarounds for both issues:

So for the SSL problem I don't know what's up with the SSL of that site. For those who are ready to take the chances of trusting this site, download the source file (http://gforge.inria.fr/frs/download.php/file/34618/scotch_6.0.4.tar.gz) into your scotch folder and run "makepkg -sri". Since the file is already there, it won't complain that the certificate of the site is not trusted.

Second, the testing of scotch involved running something on 4 processes while my laptop only have 2 cores. This was not a problem with my old installation of OpenMPI (perhaps an OpenMPI 3 thing?). If you can't run "mpirun -n 4 echo hello" then you have this problem too. However, adding "--oversubscribe" allows you to run 4 processes. I made makepkg add this flag to the test by adding a sed-line in the the check() function in the PKGBUILD file as follows:

check() {
  cd "${srcdir}/${pkgname}_${pkgver}/src"

  sed -i 's/mpirun/mpirun --oversubscribe/' check/Makefile

  make check LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:../../lib"
  make ptcheck LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:../../lib"
}

And that made it work. May I suggest adding that sed-line permanently to this PKGBUILD?

It seems that this error is because the source of the .tar.gz file used to be on an http:// adress but now it is forwarded to an https:// adress (but otherwise the same adress) and my system cannot verify the validity of the certificate. Of course, neither can I, but if you decide to "trust" the source anyway, you can download the .tar.gz-file to your clone of the scotch folder and run makepkg -sri again. Since the source file is already there it won't use curl to try to download it. That gets us one step further, but now I get this one:

mpirun -n 4 ./test_scotch_dgraph_check data/bump.grf
--------------------------------------------------------------------------
There are not enough slots available in the system to satisfy the 4 slots
that were requested by the application:
  ./test_scotch_dgraph_check

Either request fewer slots for your application, or make more slots available
for use.

I find this a bit strange since I don't normally have any problem running mpirun with 4 processes.

I get the same problem now. Is there something wrong with the SSL on that website?

I get the following:

I am unable to build this package on an up-to-date Arch system. I have pasted the last few lines of the build output below.
